Devil's Millhopper
1881
Gainesville, Florida
Public domain · Wikimedia Commons
A 120-foot sinkhole with a miniature rainforest growing in its cool bottom, fed by little waterfalls off the rim, which has been a tourist attraction since the 1880s. The name is a frontier joke: fossil bones and teeth found at the bottom meant the funnel-shaped hole must be the hopper feeding the devil's grist mill. It is 232 steps down and the same number back.
That was 1 of the hidden places.
